[Tests] gettimeofday syscall test hangs with ETHREADS=1 #380

hukoyu · 2020-06-04T05:36:28Z

This test fails in sgx-lkl nightly pipeline. In the pipeline it fails since test harness times out after 5 minutes. But when run locally it hangs forever. gettimeofday is called infinitely

Command:
SGXLKL_ETHREADS=1 make run-hw-single-gdb test=/ltp/testcases/kernel/syscalls/gettimeofday/gettimeofday02

Output:

 SGXLKL_VERBOSE=1 SGXLKL_KERNEL_VERBOSE=1 SGXLKL_TRACE_LKL_SYSCALL=1 SGXLKL_TRACE_SIGNAL=1 SGXLKL_ETHREADS=1 make run-sw-single test=/ltp/testcases/kernel/syscalls/gettimeofday/gettimeofday02

@SeanTAllen I thought #334 is fixed with your PR #372
But debug command I shared in the description of this issue, it reproes 100% locally.

@SeanTAllen this reproes with run-sw more easily.
SGXLKL_ETHREADS=1 make run-sw-single-gdb test=/ltp/testcases/kernel/syscalls/gettimeofday/gettimeofday02

SeanTAllen · 2020-06-04T10:04:31Z

That error message no longer exists. If you are still getting an error related to next_delay_ns then you aren't running the most recent code.

hukoyu · 2020-06-04T21:49:21Z

@SeanTAllen I cleaned and rebuilt with latest code. Yes I don't get this error now but it makes gettimeofday system call infinitely, never stops.

I ran command:
SGXLKL_VERBOSE=1 SGXLKL_KERNEL_VERBOSE=1 SGXLKL_TRACE_LKL_SYSCALL=1 SGXLKL_TRACE_SIGNAL=1 SGXLKL_ETHREADS=1 make run-sw-single test=/ltp/testcases/kernel/syscalls/gettimeofday/gettimeofday02

It makes this system call infinitely: (This line repeats millions time)
[[ LKL SYSC ]] [tid=1 ] gettimeofday 169 (140321962060832, 0, 0, 0, 0, 0) = 0

SeanTAllen · 2020-06-05T11:15:24Z

I'm able to reproduce locally.

SeanTAllen · 2020-06-05T11:31:39Z

Interesting. The basic/clock test that also calls gettimeofday does not hang.

SeanTAllen · 2020-06-05T11:37:20Z

@hukoyu ok, so this is probably related to #209.

The problem is that with 1 thread, the timer never goes off to end the test.

But, it only happens with 1 ETHREAD.

Was this test ever working before or was it always dying on startup due to next_delay_ns bug?

test code is here:

https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/gettimeofday/gettimeofday02.c

hukoyu · 2020-06-05T16:02:09Z

@SeanTAllen yes it only fails with ETHREADS=1. It was failing in sgx-lkl nightly pipeline where we run tests with different ETHREADS values like 1, 4, 8. This test was always failing.

SeanTAllen · 2020-06-05T16:04:32Z

How could CI be passing if this has always failed for all different numbers of ethreads?

I think I'm misunderstanding you.

hukoyu · 2020-06-05T16:27:24Z

@SeanTAllen normal sgx-lkl pipeline runs with ETHREADS=cpu core count (which is 4 or 8)
It passes with ETHREADS=4 or 8

In nightly sgx-lkl build we run with different ETHREADS (1, 4, 8) and it fails for only ETHREADS=1

SeanTAllen · 2020-06-05T16:37:35Z

Gotcha

letmaik · 2020-06-05T17:15:20Z

(@hukoyu The normal pipeline uses ETHREADS=8 for everything. See also the default in template.yml.)

SeanTAllen · 2020-06-09T21:08:50Z

So the problem here is with the cooperative scheduler.

The test in question will never yield the CPU. It calls gettimeofday repeatedly and there's nothing in the existing LKL codebase that will cause it to yield.

It works with more than 1 ETHREAD because, another core is available that will receive the signal from alarm and terminate the test.

I'm looking at how lthreads might occassionally yield to allow for other jobs to be done.

It might take a while to come up with a satisfactory solution.

letmaik · 2020-06-10T09:54:04Z

I'm marking this as p2 since using a single ethread is an edge case which likely won't ever be used in deployments.

SeanTAllen · 2020-06-10T11:18:48Z

I agree that single ethread can be considered an edge case. I do think that the underlying issue needs to be addressed as it can reappear with more ethreads and the correct program. Unless a thread in a user program calls sleep or similar, it won't yield the scheduler so if there are more of said user threads than ethreads, progress will probably halt.

We need additional cooperation points in the scheduler to make the cooperative scheduling better especially as the Linux programs that we are attempting to run were written with a preemptive scheduler in mind.

SeanTAllen · 2020-06-16T10:22:14Z

There's a tester application for this on the seantallen/380 branch.
